mode. In this case, you can force the port to transit to the MSTP mode by performing
the mCheck operation on the port.
Similarly, a port on an RSTP-enabled switch operating as an upstream switch turns to
the STP-compatible mode when it has an STP-enabled switch connected to it. When
the STP enabled downstream switch is then replaced by an MSTP-enabled switch, the
port cannot automatically transit to the MSTP-compatible mode. It remains in the
STP-compatible mode. In this case, you can force the port to transit to the
MSTP-compatible mode by performing the mCheck operation on the port.
1.4.1 Configuration Prerequisites
MSTP runs normally on the switch.
